IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of'. Letters Patent No. 138,923, dated May 13,1873; application filed October 21, 1872.

To all whom it may concern;

Be it known that I, FRANKLIN G. PALMER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Burner; and I do hereby .declare that the following is va full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a section taken diametrically through the burner. Fig. 2 is a bottom view of the burner-cap. Fig. is a top view ofthe perforated tube on which the cap is applied. Fig. 4 is a bottom View of `the generator with the arms of the spider broken olf.

Similar letters of reference indicate correspondin g parts in the several figures.

This invention relates to a new and improved vapor-burner for generating and burning vapor from hydrocarbon-oils, wherein I combine with a gas-generating tube an adjustable perforated air-mixing tube, in which is a valve for regulating .the escape of the inilammable gas from the said generating-tube.

The valvular device in my invention is of great importance. It is the only valve or cock that does away with an open joint or joints tightened by a stuffing-box or ground or threaded joints, which, after using a short time, are liable to leak from the friction produced by adjusting the valve, thus obviating the one great objection to hydrocarbon-pressi ure burners, viz., their liability to leaky joints.

The following description of my invention will enable others skilledv in the art to understand it.

In the accompanying dra-wing, A represents the generator, which is screw-threaded for receiving upon it a tube, B, of a burner. The ,oil from the lamp passing into this tube is therein converted into gas, which passes through the perforation c into the mixing-chamber h, in which chamber the gas becomes mixed with air which passes through perforations e from outside. The generator A is packed with straight wire or wick, as indicated at z z in Fig-1, which packing so retards the passage ofthe iluid used as to cause a steady flow of gas through the orifice c into the mixing-chamber h. At the upper end of the orifice c is a valveseat, g, which may be closed by a valve,pcl, on a stem or spindle, d, when it is necessary to extinguish the flame. This stem cl, with its valve d', is also used as a cock to shut off the flow of the gas through the orifice c when desired. This valvular device may be elevated or depressed by turning the tube B, and so more or less of the gas allowed to escape from the chamber a of tube A into the chamber h of tube B. The tube B has applied to it at its base the arms C for adjusting the spindle. At the upper end of this tube are several perforations; those perforations which are lettered j j allow the gas to escape from chamber h into the hollow slotted head D of the burner, while those which communicate with the perforations j from without, lettered l' t, are for the purpose of allowing the escape of small jets of gas, which, when ignited, will cause heat enough about the tube A to generate the gas therein.

The valve-rod d is secured to the tube or burner-top B, so that by simply turning the latter the size of the flame may be regulated. In order to supply oxygen to the gas in the chamber 7L of tube B, I perforate this tube around its lower screw-threaded portion, as shown at e, which will allow air to enter the mixin gchamber h in proper quantities. These openings I locate below the plane point where the gas issues from or through the opening c. Such location of the air-passage c permits me to so shorten the length of the air-mixing chamber H as to bring the heat of the burning gas at ti near downv to the gasgenerating chamber A. vIf the air-openings were on or above the plane where the vapor or gas issues from or through the opening c, and the mixing-chamber made as short as I am enabled to make'it with the air-openings below, as e, the vapor would be liable to escape through the air-openings instead of passing up through the burner-top D.

What I claim as new, and desire to secure by Letters Patent, is-

The spindle or spindle-point l d', attached to or forming part of a burner or burnertop, inverted and above the generator, and acting as specified, all substantially as set forth.

FRANKLIN G. PALMER.
